Perfect upgrade for abrasive filaments
Switched to this hardened steel nozzle assembly specifically for printing carbon fiber filled PLA. The integrated throat design eliminates the gap where clogs used to form. Print quality is exceptional and installation was straightforward.

No more clogs!
I was experiencing frequent clogs with my previous setup when printing high-temperature materials. This TZ4.0 assembly solved the problem completely. The metal throat conducts heat much better.

Good product, shipping delay
The hotend itself works great and fits my P1P perfectly. However, the shipping took longer than expected. Once installed, though, the prints are crisp and consistent.

Great performance, slightly tight fit
The print quality improved immediately after swapping out my stock hotend. The only minor issue was that the assembly felt a bit tight going into the heater block, but once seated, it works flawlessly.

Essential for X1 owners
If you plan on doing any serious engineering material printing on your Bambu X1, get this. The durability of the hardened steel nozzle is worth every penny. Saves time on maintenance.

Seamless replacement
Replaced my worn-out stock hotend with this unit. The calibration process was quick, and the first print came out perfect. Highly recommend for anyone needing a reliable replacement.
Q: Is this compatible with the Bambu Lab A1 mini?
A: No, this TZ4.0 assembly is specifically designed for the X1, X1-Carbon, P1P, and P1S series. It is not compatible with the A1 or A1 mini models.
Q: Can I use this with standard PLA without changing settings?
A: Yes, you can use standard PLA. However, because this is a hardened steel nozzle, you may need to slightly adjust your flow rate or temperature compensation in your slicer profile for optimal results.
Q: What is the difference between TZ4.0 and the stock hotend?
A: The TZ4.0 features an integrated metal throat which reduces the risk of clogging at the junction between the throat and nozzle. It also uses a hardened steel nozzle by default, making it suitable for abrasive filaments.
Q: How often should I replace the nozzle?
A: With the hardened steel nozzle included in this assembly, lifespan is significantly longer than brass nozzles. For non-abrasive filaments, it can last indefinitely. For abrasive materials like CF-GF, inspect every 500-1000 hours.
Q: Does this come with a silicone sock?
A: This package includes the complete hotend assembly with the hardened steel nozzle and integrated throat. The silicone sock is usually transferred from your old assembly or sold separately depending on the specific bundle.
